Referring in the first instance to i 23, tml 3 oi' the drawing, i represents the Lipper portion oi a jar having a iat top surrounding the mouth, and having seats-:i upon a oever 2 whereby the closing oi the jar is nested, this cover being 'made of metal, er, orotheravailableiiiaterial, and g, elesirerl, coated. with paraiii or tile like, iii weer to aid inA forming a hermetiealiy sealed i ist 'between the vcovei' ari-el its seat. around the imper end of the-jar is ari interw rupted ril), tllieiiiterruptions hei-iig preterffely formed by making some portions Stef the rio, thiriiier'than the other ortioiis 3 oi the saaie, and, in the under si e of each of the thicker `portions 3 of the rib, is formed a iiotehe, as shown-in Fig. 2. iii Connection with the jarshown in Figs. i, Zend 3 i use a A m the term of im inverted esp, having j relied .its lower edge as many inwardly proH feet/ine iirivere t esthereere eotenes is. the

The eiastie iisl; 'Z is irei'erahly siitted, and its re silieiiey is sueh thaty when the 'fingers of the iii tim iioteiies Lt, suiiieieiit i opor the eover 2 to ooiitaot of said cover eel fiese L l 7 i have ilhistrated the ep invention that Class oi eastie peeking ring 'lO or dish is seated upon. an iriteriiai shoulder helow the o' the jsr, aio ring or disk folios-tion oi 'being bashed by a eover 522L ei' or other relatively rigid material, through the 1iierliurii oi whieh the 'pressure oi the spring ineiiiher 7 oi' the elosure is im iartei'l.

in Fig. i have illustrateci another embodiment of my invention, in' which the mouth portion ol' the ier is recessed l'or the reception el' a oever 2b, oi' ghiss or other available material, iii order to prevent aooessoi' the contents oi the jarjto the packing ring l0, which is seated upon the top oi' the jar, and, this embodiment oi' my iiiverition I have also shown the cap 5L as provided with a Central depression 7, which eonetitutes the elastie member oi the re tailler, the eepheing made of material possessmg suoli resiliency es to render this porportions f the retaining member oi' the closure in the `i'or bearing directly on the cover 2 ci the jar,

' pressure, thus preventing the breaking ol the tion 7'a capable of exerting the desired yieldressure upon the rigid cover 2b.

ile I prefer, in most cases, to construct form of a cap, this is not absolutely essential to the proper carrying out of my invention, as a yoke carrying the spring member and having the desired number of arms `l'or engagement with the notched rib oi the jar may be employed in place of such closed cap., if desired, such construction being illustrated at 11, in Fig. 6, or I may use a sin le bar yoke 12, as shown in Fig. 8 said yoke aving fingers engaging with notchesA in a continuiL ous rib on the jar, and being depressed in the center so as to form a spring member 7b and this yoke' may be mounted upon the cover, if desired, as for instance by riveting it thereto', as shown at 1.3.

The thickened members 3 ol' the rib shown in Fig. 2 have abrupt ends, but they may, in some cases, be provided with inclined portions 14 leading to the notches, as shown, vl'or instance, by dotted lines in Fig. 7, the engagement oi the fingers 6 of the retainer with these inclined portions serving to cause the depression of said retainer as the latter. is turned a'l'ter being applied to the jar.

A closure constructed iii accordance with my invention can be cheaply made, it provides a neat and attractive finish for the top of the jar, and, `when the retainer is in the l'orni oll a closed cap, it serves to protect the cover, or cover and spring, from injury or displacement. Owing to the `fact that the I cover ol' the jar is held in place under a yielding pressure, any expansion ol' the contents ol a l'ull jar, either byhcat or cold, which is suliicient to exert a prepoiulerating upward pressure. on the cover, will cause said cover to lil't and relieve the excessive internal The notches in the under side ol` the thickcued portions ol the rib which surrounds the mouth oll (he jar extend to the outer l'ace ol" said rib, and consequently do not interl'ere g with the partinfr ol' the mold in which the i jar is formed. ihe notches l'or the reception 1 ol the lingers oll the retainer may be formed in a member separate vl'roni the jar, as shown l at l5 in Fig. 4, instead ol' in a rib integral i name to this speciiicatiom'in the 'with the jar, said -member either extending completely around the jar or only so far around the same as to prevent its lateral removal, as preferred.

1. A jar having, around the-mouth,a rib with notches in its underside whiehnotches have abrupt side walls, a cover for said jar, a retainer extending over said cover and having inwardly extending iingers for entering said notches, and also having an elastic member extending downwardl from the retainer and having only a limited bearing upon the cover, said elastic member of the retainer exerting downward pressure upon said cover and upward pressure upon said fingers.

2. A jar having, around the mouth, a rib with notches in the underside of the saine, which notches have abrupt side walls a cover for said jar, a retainer having fingers for entering said notches, and also having an elastic member secured to the underside of 'said retainer, said elastic member exerting downward pressure upon said cover and upward pressure upon said in ers.

3. A jar having, around t e mouth, a rib with notches in its underside, which notches have abrupt side walls a cover.for said jar, a retainer having fingers for entering said notches, and an elastic member securedto' thel underside of said retainer, said elastic member bearing upon the cover immediately above its seat 4upon the jar, and exerting downward pressure upon said cover and upward ressure upon said fingers.

4. ii) jar having, around the mouth, an interrupted rib with notches in its underside, which notches have abrupt side walls, a cover lor said jar, a cap having inwardly projecting lingers for entering the notches, and an elastic member secured to the underside ol' said retainer and exerting downward pressure upon said cover and upward pressure upon said fingers.

In testimony whereof, I have signed my presence ol two subscribing witnesses.
